Endometrial biopsies were taken for histological assessment from 97 cows which calved in a commercial dairy herd between April and August 1984. The main objectives of this study were to analyze the interrelationships among histological criteria and to identify a shortlist of histological parameters to be included in subsequent analysis of associations with results of bacteriological culture, clinical findings and reproductive performance. Epithelial height and segmented cell counts were highly correlated within biopsy, between horns and between days. Subjective assessment of inflammation in the epithelium and/or stratum compactum generally identified biopsies which had any inflammation present. Cows which had inflammation in a biopsy from day 26 were likely to show inflammatory changes at day 40. Quantitative and subjective assessments of gland number, dilation and fibrosis were highly correlated. There was a positive association between the number of cross sections and the diameter of glands, and both of these criteria were negatively correlated with fibrosis and inflammatory changes. There may be different functional significance of the same histological finding at a different number of days postpartum.
1984年4月至8月间，从一个商业化奶牛场分娩的97头母牛身上采集子宫内膜活检样本进行组织学评估。本研究的主要目的是分析组织学标准之间的相互关系，并确定一份组织学参数清单，以便在后续分析与细菌培养结果、临床发现和繁殖性能的关联时纳入。上皮高度和分段细胞计数在活检样本内、两角之间以及不同天数之间高度相关。对上皮和/或致密层炎症的主观评估通常能识别出存在任何炎症的活检样本。在第26天活检有炎症的母牛在第40天可能会出现炎症变化。对腺体数量、扩张和纤维化的定量和主观评估高度相关。横截面数量与腺体直径呈正相关，且这两个标准均与纤维化和炎症变化呈负相关。产后不同天数相同组织学发现可能具有不同的功能意义。
